With so many services and games coming up that require your vote to use, I'm beginning to see this as unsustainable. Those who don't use a service and see the post as over-valued will simply down-vote the post. I think people should start charging users for using services and playing games so that the reward pool can be used to benefit the entire community, not just those who participate in a game or service.
I love the sound of the app you're developing though and would be happy to pay for it rather than drain the reward pool (of money that just doesn't belong to me)
